According to the latest survey report JFUnited Consulting Co., Ltd. (JFUnited) "2007 Chinese industrial switching power supply market research report "data show that in 2006 China's industrial switching power supply market size of $ 6.7 billion; view from the installation of 2006 industrial field flatbed switching power supply and rail switching power supply products accounted for 66% and 34% of the total market size; classification from the applications point of view, the three major areas of mechanical, electrical and rail accounted for 90% of the switching power supply market in the industrial field , two major areas of mechanical and electrical accounted for 80% of the overall size of the market.
Under JFUnited survey report data show that in 2001-2006, accounting for a major share of the domestic industrial switching power supply manufacturers, such as the growth rate of the major manufacturers of Chaoyang, Ming-wai, Heng Fu average between 15% -30%, but from the entire the industry point of view, the industrial switching power supply did not achieve the expected growth rate of industrial switching power supply market growth rate is much lower than in the communications and home appliances, computer field, the 2001-2006 industrial power growth rate maintained at 10% -15 only % increase in range. In addition, JFUnited survey report pointed out that the domestic industrial switching power supply 2005-2006, the overall market growth rate of slightly more than 30 percent are optimistic about the development of the industrial switching power supply market, and in 2007. With the rapid development of the power rail switching power supply module switch, as well as the emergence of new technologies, the switching power supply of the domestic market structure will change, switching power supply manufacturers at home and abroad the expected growth rate is locked in the 20%, JFUnitedthat industrial switching power supply with a flatbed future pace of development will be maintained at about 20%, the rate of growth and the level of development of China's industrial switching power supply is much lower than in Japan, the United States, Europe and other places.
Foreign companies such as ABB, Omron, Siemens, Phoenix and other major rail products production and sales-based representative of the domestic companies such as Chaoyang, Ming-Wei (Taiwan), Heng Fu Dechuang, three groups such as the production of flat switching power supply based. In addition, foreign companies, in addition to electric Shenglan switching power supply and a few other enterprises in mainland China to set up factories, most of the imported form of sales in the mainland, on the marketing model, industrial switching power supply enterprises showed the coexistence of both agents and direct mode.
The survey report data shows that the main enterprise market scale performance switching power supply for industrial use, the top four only Chaoyang a domestic enterprise, while the other three are foreign-owned enterprises (including Taiwan), and the sunrise is not obvious advantage than the other three companies other domestic enterprises are mostly kept at a moderate level. Industry sales volume before four in Chaoyang, electric Shenglan, Ming-wai, Omron four companies market share accounted for the entire industrial switching power supply market share of 48%, indicating that the industrial switching power supply industry market concentration is already high, The development of the market is more mature level of development. The top ten enterprises in the total domestic enterprises and foreign-funded enterprises the total ratio of 1: 1.5. As can be seen, is currently lagging behind in the domestic industrial switching power supply market, domestic enterprises largely foreign-funded enterprises.
Industrial switching power supply on the price performance of the various manufacturers, JFUnited report pointed out that the price level differences between different power supply manufacturers of similar specifications (the same power and output voltage) is large, the gap in the times to ten times ranging; addition, the same company due to the number of certifications and the types of differences, the same specifications, product prices will have a very different, or the same company lead to huge price differences due to the different positioning of product applications, such as the Chaoyang military grade switching power supply industrial grade and commercial-grade switching power supply 1.5 -3 times the price difference.
JFUnited future domestic industrial switching power supply industry key competitive factors analysis in the survey report pointed out that domestic enterprises engaged in industrial switching power supply, there is a gap with foreign enterprises in terms of the overall size of the product and the product range is impossible to take into account all industrial field, strengths focus on their own areas of expertise, such as Wuxi Yufeng focus in the power industry, with international enterprises from the extension of the high-end market to the mid-market, and increase the impact of domestic enterprises, domestic enterprises to keep existing position to become the primary task, whether further market segmentation to increase the advantages of a combination of resources, the biggest challenge for domestic enterprises in the future development.
With the implementation of the Chinese localization development strategy the electric Shenglan, Omron international industrial power giant, and mergers and restructuring of domestic enterprises, industrial switching power supply products in China highlights the advantages of strategic marketing and cost, not only for the domestic enterprises impact, will further to usurp other high-end foreign brands in the field of market share.
From the point of view of industrial switching power supply market segments, electricity, railways, military, aviation and other fields, mainly monopolized by a small part of the power supply supplier, so that the characteristics of the market in the short term will not change much, the terms of industrial areas, involving products and The environment is more complex, each vendor has different proportions involved in the future, as technology and product development of the various suppliers, market share may be a larger change, Industry development level is good or bad development is particularly important for industries and enterprises, with the rapid development of power electronics technology, a variety of electronic and electrical equipment in the field, program-controlled switchboards, communications, electronic testing equipment power supply, power control equipment, etc. are widely used switching power supply, switching power supply showed alternative linear and phased power trend, the future development of space will reach or exceed the expected level, will determine the speed of development and the future trend of industrial switching power supply enterprises.
In product quality and technically domestic enterprises and foreign enterprises can not want to comparable, but because of China's cheap labor and raw materials, products price plays a very big advantage. This makes the overall size of the domestic small private enterprises also occupies 20% of the size, price and cost factors in the short-term is still one of the most important factors of the domestic competition.
Compared to domestic and foreign companies lose a considerable level in the process, the domestic switching power supply enterprises in size and value, compared with foreign enterprises. Also got some independent technical process, but mainly on a small device products. Rely on foreign technology but also in large-scale device chip technically in the Pearl River Delta region, despite a large number of Taiwanese and Japanese companies to establish production line, but the main chip technology or foreign control. Future competition, an independent technology is the key to switching power supply enterprises to master and expand the market.
JFUnited investigation report concluded that the gap the domestic switching power supply enterprises and foreign-funded enterprises also business development capabilities. Most external channel scarce resources, can only wait for customers to come to the U.S. and European companies with more complete and timely demand information channel network marketing ability is far stronger than domestic, domestic enterprises and foreign-funded enterprises, the prevalence of consciousness is not strong, and do not pay attention to the phenomenon of the relationship to maintain customers. Even some small businesses too pursuit of economic efficiency, while ignoring the related services, such as product quality assurance and after-sales service, the enterprise should bear social responsibility. This result must ultimately is The enterprise customer complaints more and more, and finally out of the market. Future competition, marketing ability and awareness is also an important factor of the enterprise development.

US-exposed Chinese top nuclear submarines: U.S. military is difficult to detect
United States, "Strategy Page" website published an article, "It's out of there quietly, very quiet (It'sQuietOutThere TooQuiet)", the article describes each of the diesel-electric submarines and nuclear submarines advantages and disadvantages, cited the country against the United States, China, Iran and North Korea, the three submarines use to disclose details of the lease Swedish submarine anti-submarine warfare tactics and equipment in the United States.
The U.S. Navy still argue the operational effectiveness of conventional submarines, as well as whether to buy conventional submarines. This happens for two reasons, one, the current U.S. Navy may not be able to maintain 40 to 45 attack submarines, the quiet performance of modern diesel-electric submarines stronger than nuclear submarines, especially in coastal waters. The use of the modern passive sensor supplier, a diesel-electric submarines underwater movement is the best weapon to attack other diesel-electric submarines. -Sea combat nuclear submarine is more suitable, in particular the need for the long voyage to reach issues waters, but the diesel-electric submarines in the coastal waters with a battery-powered voice is very small, it is difficult to be detected.
Currently, there are 39 countries equipped with approximately 400 diesel-electric submarines, but only China, Iran and North Korea against the United States and its allies plan to use its submarines. China has 50 diesel-electric submarines, Iran and equipment 3 (additional 25 mini-submarine), North Korea has 20. The United States must be considered against 73 diesel-electric submarines and 75 mini-submarines, more than half of these submarines, old and obsolete, voice, only 36 full-size submarines and 40 mini-submarine can be a real threat to the U.S. military, but if taken lightly, old submarines You can also pose a threat. Therefore, East Asia and the Persian Gulf region is a dangerous place for U.S. warships.
The past 10 years, the U.S. Navy has been assessing the submarine threat facing, from 2005 to 2007, the United States leased a Swedish Submarine (Swedish only equipped with a five submarines), employ a submarine crew want to set in the imaginary enemy as an exercise to help U.S. anti-submarine forces to study the anti-submarine tactics, and as a preferred mode of training. Sweden's Gotland (Gotland) class submarine displacement of 1500 tons, 64.5 meters long (200 feet), containing members 25 are generally small submarines, currently moored in San Diego, a 36 U.S. organizations responsible for the maintenance of the submarine maintenance.
Before the introduction of the "Gotland class submarines, the U.S. Navy has been using the Australian submarine training often fails, but the submarine. "Gotland" class submarines equipped air independent propulsion system (AIP), the good performance of underwater noise reduction, longer battery life, so similar to the face and the future of the U.S. surface ships or submarines opponents. Opponents such as Iran and North Korea are not equipped with AIP submarine, but has enough diesel-electric submarines, the crew trained, quite deadly threat.
Based on the lessons from Australia and Sweden submarines, the U.S. Navy has secretly developed a new anti-submarine tactics and equipment, confirm that the modern diesel-electric submarines still the main threat of the U.S. surface ships and submarines. Potential opponents at the same time, the construction of more affordable diesel-electric submarines, being trained crew tracking the ability of American warships. The increasing number of enemy submarines, diesel-electric submarines of the United States in offshore search and there are technical problems, so the defense of the United States has been in the "limp".
China plans to exclude the U.S. Navy in its exclusive economic zone beyond its submarines have received anti-tracking training, U.S. submarines, surface ships and aircraft difficult to detect Chinese submarines. Currently, some aquatic species due to environmental organizations protest sensor manufacturer used by the U.S. anti-submarine training injury, the U.S. Navy lost underwater anti-submarine warfare training venues in Southern California.
Meanwhile, China is to increase investment in military construction, the threat of North Korea and Iran's fleet is declining. Therefore, if the U.S. Navy must pay special attention to the development of some of the diesel-electric submarines, they must be in China. Now, China will continue to develop a world-class nuclear submarines, but also did not give up the construction of a world-class diesel-electric conventional submarines.

6.45MM World's Thinnest! TCL Refresh Smartphone Slim World Record
As a human challenge the limits of a way, the phone thin and 100 meters world record, has been constantly refresh our awareness. December 4, 2012, TCL Communications the brand conference Upload to news, the latest products TCLS850 6.45MM create smart phone the ultrathin record, and for a time became a sensation in the global mobile phone industry's big news.
The slim phone means that the use of lightweight and fashion appearance, has always been the relentless pursuit of the mobile phone industry. REVIEW functional machine era, an ultra-thin V3 has swept the globe, to help Motorola achievements dominance era; IPhone4 after, ultra-thin design again rise in the smart phone market from hopeless. Smart phone in the end can do more thin? This topic has not been determined, the only certainty is that people see the ultra-thin record time and time again to be broken. Today's ultra-thin contest is one hundred meters just as World War, meter record measured in hundredths of a second, the thickness of the smartphone record has reached the level of 0.01MM, 7.1MM, 6.8MM, 6.65MM ...... after the decimal point every change represents yet another breakthrough in the scientific and technological strength, represents a business climbed to the peak. TCLS850 emergence of the phone ultrathin record leap straight 6.45MM TCL Communications finally standing on the podium of the ultra-thin cell phone records to become the top players in the field of Global slim phone, which undoubtedly is TCL The victory is also a victory of Chinese mobile phone companies.
Ordinary consumers, the thickness of the phone is just a very simple data, people who understand the smart phone industry, its meaning is difficult to use a few words speak clearly, because the slim phone is actually an international top industrial standards embodied. To use the phone so thin, the phone companies must have the strength of both hard and soft, hard power, including the battery , touch screen , camera, connectors, speakers, etc.; soft power including architecture design, thermal design, new materials technology, simulation technology, mechanical processing ... in fact, the phone thinner, more on research and development capabilities and material requirements "metamorphosis", you can say to a certain extent, the the phone minimum thickness just represents the upper limit of the enterprise's comprehensive strength. In this sense, the introduction of the world's thinnest smartphone is undoubtedly a Declaration, but also a challenge to the world that they are strong enough. Foreign brands phone robbery market profits under the status quo, this Declaration is particularly meaningful for the domestic mobile phone industry.
As ranked seventh in the world mobile phone company, TCL Communication huge success overseas, has been to become a the smartphone leader responsibility, but the two months prior to the conference of its brand, TCL's new product releases very little So there are a lot of people in the industry sent questions: TCL how could no big move for so long? Indeed, as the writer Feng Tang said, his writing is in order to eliminate the swelling of the heart, TCL also own heart swelling to eliminate, and that is its strong R & D: worldwide, TCL has, including the Silicon Valley of the United States, in Milan, Italy France Paris, Shenzhen, Shanghai, including the eight product R & D, design centers, product development personnel more than three thousand, so powerful team how could such thing as a free cooked rice? Conference of the new brand, along with a new brand manifesto "better achievements, TCL Communication of 12 new products debut, the answers to the people this time since doubts. However, many people also "got it right at the beginning, but did not guess the outcome" - think of TCL there will be a large number of new products launched, but did not think the phone ultra-thin record.
Carefully concern TCLS850 also find this phone connotation than in the ultra-thin, and the market normalizing the several slim phone S850 4.7-inch HD screen resolution of 1280 × 720, can be said to stand out; TCL specific nano waterproof fingerprint technology is unique to this one; 4.5 seconds faster boot further thin the icing on the cake ...... a world record is sufficient to Swordsman, but TCL did not meet, but also to the many differentiated The selling point to consolidate market advantage, which show up, may be the ambition of its campaign to market. All in all, for the smart phone market in 2013, TCL Communication's performance is definitely worth the alert to all opponents.

Lithium Battery Manufacturers Accused of Price Fixing
The high cost of batteries has been the prime criticism against calls for electric vehicles (EVs) to replace conventional petrol-powered vehicles on the world’s roadways. Presently, car buyers pay a $10,000 to $20,000 premium for EVs over conventional gas vehicles, largely due to the cost of lithium batteries. This costly premium has hindered EV sales and cast doubt on the future of long-term demand.
The results of a 2011 Pike Research poll show that 40 percent of respondents would be "extremely or very interested in purchasing [a highway-capable plug-in electric vehicle] assuming the price were right." The study points out that "price sensitivity is an issue that continues to loom over the [EV] industry, as survey participants' willingness to pay was much lower than the prices currently planned by automakers."
In recent weeks, the high cost of lithium batteries has become the subject of a series of lawsuits targeting high-profile Japanese and Korean battery manufacturers, including Panasonic (NYSE:PC,TSE:6752), LG (NYSE:LPL), Sony (NYSE:SNE,TSE:6758), Samsung (LSE:BC94), Sanyo and Hitachi (TSE:6501), which together control the majority of the global battery market. In 2011, the worldwide market for batteries was reportedly worth $14 billion and is expected to total $16 billion for 2012.
While the class-action lawsuit brought against failing lithium battery maker A123 Systems (OTC Pink:AONEQ) has dominated battery investment news headlines of late, as of October 23 of this year a total of 10 lawsuits against the world's leading battery manufacturers had been filed in US courts, according to a report in the New Jersey Law Journal. The lawsuits allege that over the past decade the companies and their American subsidiaries have actively conspired in a price-fixing scheme that has resulted in consumers paying much more than they should for lithium batteries and the electronic devices they power, such as laptops, cell phones and digital cameras.
The plaintiffs claim that the price-fixing scheme first began in late 2001 or early 2002 following a nearly 50-percent drop in lithium-ion battery prices brought about by new competition entering the market. The dramatic price slide allegedly drove the world’s leading battery suppliers to enter into a price-fixing agreement that led to an almost 66 percent drop in battery production. The plaintiffs believe this scheme is responsible for the dramatic rise in battery prices seen over the past 10 years.
The allegations aren't far-fetched. Electronics companies have been the subject of several price-fixing investigations conducted by the United States and the European Union in recent years. For example, in December 2011, eight LCD panel manufacturers, including LG, Sharp (TSE:6753) and Samsung, agreed to pay a combined $388 million settlement after being found guilty of price fixing, which drove up purchase prices on screens and the products containing them from 1999 to 2006. The litigation was first brought to court in 2007 following an investigation by the US Justice Department.
The plaintiffs in the current lawsuits "assert the alleged battery price-fixing scheme has similar features: a highly concentrated market, controlled by Asian corporations; pricing pressure exerted by equipment manufacturers; rapid commoditization of new technology; and pricing behavior inconsistent with a competitive market," wrote the New Jersey Law Journal's Mary Pat Gallagher.
Although the lawsuits center on the personal electronics industry, news of the pending litigation has sparked discussion among EV market watchers, including Digital Trends' Jacob Joseph, who pointed out that "breaking up a potential price-fixing racket in lithium-ion batteries could be a significant development for EVs … prices have been predicted to fall for lithium-ion EV batteries over the next decade, but with sales of EVs falling well short of the high expectations of just two years ago and automakers rethinking their EV strategies, a decade from now might already be too late to save the EV. Should these suits trigger a worldwide drop in lithium-ion battery prices, the potential is there for an EV market which is competitive with standard gasoline-powered cars."
Any improvements in the medium- to long-term demand picture for electric vehicles bodes well for overall demand in the lithium market, making the outcome of these class action lawsuits something lithium resource companies and their investors will want to track. Lithium Investing News will continue to follow developments as well, so stay tuned for updates.

The results of a 2011 Pike Research poll show that 40 percent of respondents would be "extremely or very interested in purchasing [a highway-capable plug-in electric vehicle] assuming the price were right." The study points out that "price sensitivity is an issue that continues to loom over the [EV] industry, as survey participants' willingness to pay was much lower than the prices currently planned by automakers."
